Your figure should now be dry and quite sturdy to work with.
To make the base for your figure to stand on take a box, punch holes in the top and feed the wire attached to the feet through the holes. Fill the box with something heavy to add weight as this will balance the figure when complete. I used some broken terracotta pieces from a garden pot.
Using the same technique cover the box with plaster bandage until it is completed covered and your figure stands upright.
Leave the whole thing to dry.
If you want you can stop at this stage although I’m going to add an extra stage with plaster paste to try to erase the bandage texture a bit but will need to leave this to dry first.
